§6.1 Angle of elevation and tangent

Let's make a start together!

Let's have a good look at the Theory:

So remember:

The steepness of a slope/angle we call:

+ gradient or

+ tangent (tan)

Homework time.

Study square is open.

Good luck everybody!

Later on this LessonUp goes on.

How to do exercise 5?

Let me show you the Method to tackle it,

then you can do the exercise yourself!

See next slide.

Task:

Take your calculator and try to get 22 degrees as an answer!

In the next slide I will show you how to key this in.

Solution previous slide:

tan angle A =  

Key in this:        

                        =                                         =   22 degrees

So: keyword is: brackets!   Now a Joke.
